How does IMV differ from CMV?

• A. IMV allows for spontaneous breathing between mandatory breaths
• B. CMV requires patients to breathe spontaneously
• C. IMV is suited for anesthetized patients only
• D. CMV always uses a decelerating ramp

Answer: (A)

IMV, or Intermittent Mandatory Ventilation, is designed to allow patients to breathe spontaneously between mandatory mechanical breaths. This means that while the ventilator provides set breaths at specified intervals, patients can also initiate their own breaths without the need for mechanical assistance during those periods. This feature provides a level of autonomy and comfort for the patient, particularly in scenarios where they are able to maintain some degree of respiratory function. In contrast, CMV, or Continuous Mandatory Ventilation, requires that all breaths are delivered by the ventilator, with no allowance for spontaneous breaths by the patient. This mode is often used in patients who are unable to breathe on their own and need full ventilatory support. Understanding this fundamental difference highlights how IMV can be beneficial for patients who are transitioning from reliance on mechanical ventilation to spontaneous breathing, making it more versatile in various clinical settings, unlike CMV, which is more stringent in its requirements.
